Sample reactions for this molecule:
Digestion of linear starch (amylose) by extracellular amylase
Digestion of 1-6 linkages of limit dextrins to yield maltose, maltotriose, longer maltosides, and glucose
maltotriose + H2O => maltose + D-glucose (sucrase-isomaltase)
Digestion of branched starch (amylopectin) by extracellular amylase
maltotriose + H2O => maltose + D-glucose (maltase-glucoamylase)
Defective SI does not hydrolyze maltotriose
